Abstract
The investigation of radiation-durable materials with outstanding gamma shielding
capabilities and lead-free alternatives remains a compelling area of research.
This study fills a critical gap by exploring, for the first time, the radiation attenuation
properties of the novel material Aluminum Oxynitride (AlON) and its
shielding mechanism. Utilizing the XCOM database and Geant4 Monte Carlo
simulation toolkit, we systematically examined AlON’s linear attenuation coefficient,
mass attenuation coefficient, half-value layer, tenth-value layer, mean-free
path, effective atomic number, and effective electron density. Comparing AlON
to traditional shielding materials and glasses, including both lead-containing
and lead-free compositions, our study suggests its superiority over concrete and
lead-free glasses. At higher energies, AlON demonstrates comparability with leaddoped
materials. These findings contribute valuable insights into the potential
applications of AlON across diverse radiation shielding contexts. This research
provides a foundational understanding of AlON’s radiation attenuation capabilities,
paving the way for future exploration and practical applications in the field
of gamma shielding.
